My RAZR V3 Cellular Phone blinks on and off when turned on both when open and closed and the battery do not hold up charge for long

you miqht have water damaqe.

the v3 is known for battery issues. not charging, not holding charge and overheating. my suggesting is get a different model phone. and stay away from razors. they all have battery issues, I know this from multiple customer razor issues. all battery issues.

It sounds like a stuck button to me since you said there's no signs of liquid damage. I used to diagnose and repair cell phones. With the phone off, just press every button in various angles [instead of straight down]. I hold the phone like Im talking on it, then use my thumb to rotate it around the menu navigation buttons. I would focus on the buttons used to navigate through the menu, then move to the other buttons. Power phone on and test it out. If this doesn't work, then its probably a software glitch as Razr phones are known to have those from time to time. I would then go back to where you got the phone and have them replace it under warranty if you got it within the year. If they won't for whatever reason, get a hold of Motorola and make them repair/replace it under their warranty [as they are the ones who warranty it for a year anyways]. Most cellular companies have policies to exchange defective phone out if within manufacturing [This case Motorola's] warranty.

Their website says only 6 hours of talk time for that battery. Could be that's all your gonna get from it. Every phone I've ever owned has needed to be recharged every other day and sooner if it's used more.

Pull out the battery *while the phone is on*. Wait 15 secs then put battery back in and turn phone on. That should fix it.

HAS IT BEEN WET? IF SO OPEN BATTERY DOOR AND REMOVE BATTERY THEN POUR RUBING ALCOHOL NOTE MUCH THEN VACUME NOW PLACE IT UNDER POWERFUL FAN OVER NITE.TRUST ME IT WORK'S...

what you have to do is to clean your phone using isoprophyl alcohol i mean you clean the main mother board then you dry it using hair dryer ,after all that try to replace the battery it has reach it death neal the cells inside they are no longer able to hold the charge.advice by dogy.

i have noticed that the mini plug for the charger and usb connection on RAZR V3 is sometimes sloppy. when the phone is charging it will definitely say battery charging on the external display and also flash the battery icon. i also noticed that the plug for the wall outlet is touchy.
make sure the plug is secure in the wall outlet
make sure the mini plug is secure in the phone
gently wiggle these connections if you have to till you get the battery charging message
if there are any connection problems there will be a unable to charge message instead.

I had the same problem with my phone- i got a cheap generic battery to replace the old one (which wasn't holding a charge for a full day, at that) and then i lost all signal, basically. I tried what scm_pa said he did - charged my old battery up, with the phone off, till the charge was complete- turned the phone on, and voila, reception!

Ok so when I close my phone I still see the time and my background picture but no light immanates (hope I spelled that right)from the screen if thats what your saying that's normal. Now as far as the inside screen if you dropped it the connection that lets the phone know it's closed may be jarred lose and offset (not sayin u dropped it)although you say it dims. When you close your phone the inside screen should turn white and then turn off just barely have your phone open to check, if it does this then the connection is working. And you need another opinion.
